One important function of emotions is to guide decision making and behaviors for survival in complex environments. In the context of such reasoning, the somatic marker hypothesis (Damasio, 1994) has argued that bodily states are represented in specific brain regions, such as the insula, and would play critical roles in decision making. However, it still remains unclear what causal roles bodily states would play in decision making, and how the bodily states would change accompanying decision making. Thus, the aim of (...) this article is to reconsider aspects of the brain and bodily states in decision making based on recent findings. Questions for future research are proposed based on such findings. (shrink)

With the ever‐increasing lifespan along with societal changes, women can marry and procreate later than in previous centuries. However, pathogenic genetic variants segregating in the population can lead to female subfertility or infertility well before the average age of normal menopause, leading to counter‐selection of such deleterious alleles. In reviewing this field, we speculate that a logical consequence would be the later occurrence of menopause and the extension of women's reproductive lifespan. We illustrate this point with a simple model that (...) applies to other variants that contribute to female infertility, including epigenetic variation. We also consider the effect of medical interventions and lifestyle. (shrink)

The epistemology of Richard of Saint-Victor is characterised through a detailed analysis of contemplatio, the highest mode of human knowledge. Contemplatio culminates in an ecstasy, in which man reaches the highest object of his knowledge, God himself, and is fulfilled by true spiritual pleasure. This plenitude of spiritual pleasure is not just the fruit of knowledge, but fed by love. Richard distinguishes three paths of knowledge in accordance with the growth of the love between God and man. The love of (...) God gives an orientation to human knowledge. Through the love of God human knowledge is structured from disoriented cogitatio to oriented meditatio as a spiritual ascent to the divine things supported by virtues, then finally to contemplatio, which culminates in ecstasy with true spiritual pleasure. So the essence of true spiritual pleasure reflects the structural key of the highest knowledge, contemplatio, namely the love of God. (shrink)

In the trolley problem, a well-known moral dilemma, the intuitive process is believed to increase deontological judgments, while deliberative reasoning is thought to promote utilitarian decisions. Therefore, based on the dual-process model, there seems to be an attempt to save several lives at the expense of a few others in a deliberative manner. This study examines the validity of this argument. To this end, we manipulate decision-making time in the standard trolley dilemma to compare differences among 119 Japanese female undergraduates (...) under three conditions: intuitive judgment, deliberative judgment, and judgment after a group discussion. The current results demonstrate that utilitarian judgments decreased from 52.9% in the intuition condition to 43.7% in the deliberation condition and 37.0% after the discussion. Additional analysis suggests that the decrease in utilitarian judgments may be related to psychological unwillingness to assume responsibility for the lives of others rather than to an increase in deontological judgments. Finally, these results are discussed from an adaptationist perspective. (shrink)

Drawing on recent work in the contemporary philosophy of economics, this book presents new ideas on liberalism, including the concept of 'growth-oriented liberalism'. Since the end of the Cold War, questions and definitions of liberalism have moved from the sphere of political systems (the socialism versus liberalism debates) to the sphere of ethics (what it means to live in a liberal society). The chapters in this work trace the trajectory of the concept of liberalism in the philosophy of economics by (...) exploring the ideological implications of the methodological debate between socialism and liberalism, the idea of liberty as real freedom, the ethical implications of Max Weber's methodology on autonomy and liberty, and new typological theories of ideologies in the context of contemporary economic ethics. This book marks a significant contribution to the literature on liberalism in the philosophy of economics and economic methodology, and is highly recommended for readers who seek updated ideas on liberal society in its ethical and philosophical contexts. Tsutomu Hashimoto is a Professor at Hokkaido University and the President of the Synodos Institute of International Studies in Japan. (shrink)

Brain‐derived neurotrophic factor (BDNF) is the most‐abundant neurotrophin in the brain. In mammals, it is synthesized as a precursor called proBDNF, which is proteolytically cleaved to generate mature BDNF. The BDNF gene is located on chromosome 11p13, and a functional single nucleotide polymorphism (SNP) of this gene has been shown to produce a valine (Val)‐to‐methionine (Met) substitution in the proBDNF protein at codon 66 (Val66Met). Several papers suggest that this SNP is related to decreased hippocampal volume and hippocampus‐mediated memory performance (...) in humans. Recently, Chen et al.1 generated a variant BDNF mouse (BDNFMet/Met) that reproduces the phenotypic hallmarks in humans with a variant Met allele. In the behavioral analysis, BDNFMet/Met mice show increased anxiety‐related behaviors. This mini‐review examines the impact of Met substitution of proBDNF on anxiety‐related behaviors.

古事類苑、モラロジー、麗澤大学...研究遍歴と交友関係を改めて検討し、道徳の科学的研究に至る過程を描き出す。.

In his writings Philosophical Remarks, the Austrian-British Philosopher Ludwig Wittgenstein draws an octahedron with the words of pure colours such as “white”, “red” and “blue” at the corners and argues: “The colour octahedron is grammar, since it says that you can speak of a reddish blue but not of a reddish green, etc”. He uses the word “grammar” in such a specific way that the grammar or grammatical rules describe the meanings of words/expressions, in other words, how we use them (...) in our language. Accordingly, the colour octahedron can also be taken to represent grammatical rules about how we apply words of colour, e.g., that we can call a certain colour “reddish-blue”, but not “reddish-green”. In a different context, the Japanese philosopher Shūzō Kuki explores in his work The Structure of Iki what the Japanese word “iki” means. This word is often translated as “chic” or “stylistic” in English, but Kuki holds that it is an aesthetic Japanese concept that cannot be translated one-to-one, instead encompassing three aspects: “coquetry”, “pride and honour” and “resignation”. To explain the meanings of the word “iki” and other related words all of which Kuki calls “tastes”, he introduces a rectangular prism as a geometrical representation similar to Wittgenstein’s colour octahedron. In this paper, I argue that the rectangular prism does not solely explain how the modes of Japanese tastes are related to each other, but also has a grammatical character. On this score, I suggest that one can regard this rectangular prism as a description of the grammatical rules of the Japanese language. By appeal to the arguments of both philosophers and in comparison with them, I will not only clarify what they claim by geometrical representations but also examine what role this kind of representation plays as an explanation of grammar in general. Keywords: grammar, colour octahedron, rectangular prism, Shūzō Kuki, Wittgenstein. (shrink)

This is a study of 288 Korean and 323 Japanese Business executives. The result indicates that, (1) the business executives believe basically in higher level business ethics, but (2) they occasionally have to make unethical business decisions which conflict with their personal values, because of prevailing business practices. (3) However, they think higher ethical standards is useful for long-term profit and for improving workers' attitudes, and the standards can be improved, and (4) to improve ethical standards, model setting by superiors (...) is the most important and clear-cut company policies and code of ethics are essential.

Previous studies on whether punishers are rewarded by reputational gains have yielded conflicting results. Some studies have argued that punitive behaviors potentially result in a positive evaluation, while others have found the opposite. This study aims to clarify the conditions that lead to the positive evaluation of costly punishment. Study 1 utilized one-round and repeated public goods game situations and manipulated decision time for participants’ punitive behavior toward the non-cooperative person in the situation. We also asked participants to report their (...) impression evaluations of punitive behavior toward non-cooperative people. Moreover, utilizing the second- and third-party punishment games, Study 2 manipulated the decision time of participants’ punitive behavior toward the self-interested person and asked them to evaluate the punitive behavior. The results showed that those who punished intuitively were not likely to be evaluated positively. However, punishers were rewarded when the decision to punish was made after deliberation or made by those who were not direct victims. These findings extend previous research on the evaluation of punitive behavior and reveal that deliberative punishment is evaluated positively occasionally. (shrink)

We investigated the effect of culture, moral discourse, and motivation to engage in prosocial behavior on benefactors’ positive affect. Participants from three cultures responded to scenarios in which they could perform small acts of kindness for different targets. A stronger relationship between agentic and obligated motivation to perform acts of kindness, as well as between obligated motivation and positive affect, was observed for participants from Japan, and for individuals with higher endorsement of the Community Ethic. Agentic motivation to engage in (...) prosocial behavior was related to benefactors’ positive affect, regardless of relationship type. (shrink)
